    Sounds like "psychobabble" to me. I doubt that natural convection would "inflate" or "suck a vacuum" in a house. Someone is just trying to promote his "theory", and maybe some "invention", without any facts to back it up.

    His explanation and prescriptions crap.

    The "planned hole" should be a heat recovery ventilator. Otherwise you're better off completely air-sealing the house rather than poking newer-bigger holes to guarantee where the warm moist air is leaving during winter.

    High natural ventilation rates from random infiltration is a BAD idea for any home, even if you poke the holes to ensure that the bulk of the exfiltration path isn't going to cause a condensation problem. Air-tight is right, then mechanically ventilate at the appropriate times & rates.
